DETAILED DESCRIPTION

With reference now to the FIGS., a cooking system is illustrated at numeral 20. As shown, the cooking system 20 includes a base 22 and a lid 24. The base 22 includes a housing 26 having an exterior, heat resistant or non-conductive surface 28 and an interior surface 30 that defines a hollow interior 32. The housing 26 may be made of any suitable material, such as glass, aluminum, plastic, or stainless steel for example. A liner 34 may be disposed within the hollow interior 32 of the housing 26. The liner 34 may be formed from any suitable conductive material, such as aluminum for example. In an embodiment, best shown in FIG. 2, the liner 34 forms the interior surface 30 of the housing 26 (see FIG. 4) and thereby defines the hollow interior 32 of the housing 26. Alternatively, the liner 34 may be offset form the interior surface 30 of the housing 26. However, it should be understood that other components of the cooking system 20, or surfaces thereof, may also define the hollow interior 32.

In an embodiment, a cooking container 36 is receivable inside the hollow interior defined by the liner 34. Although the cooking container 36 is described herein as being removable from the housing 26 of the base 22, embodiments where the cooking container 36 is integrally formed with the housing 26 are also contemplated herein. The cooking container 36, best shown in FIGS. 2 and 4-6, has an interior 38 designed to receive and retain food support structures for supporting one or more consumable products, such as food products for example, therein. Examples of food products suitable for use with the cooking system 20, include but are not limited to, meats, fish, poultry, bread, rice, grains, pasta, vegetables, fruits, and dairy products, among others. The cooking container 36 may be a pot formed from a ceramic, metal, or die cast aluminum material. In an embodiment, an interior surface 40 of the cooking container 36 includes a nano-ceramic coating and an exterior surface 42 of the cooking container 36 includes a silicone epoxy material. However, any suitable material capable of withstanding the high temperatures required for cooking food products is contemplated herein.

One or more handles 44 may be associated with the cooking container 36 to allow a user to easily grasp and manipulate the cooking container 36. In the illustrated, non-limiting embodiment, the cooking container 36 includes two handles 44 extending from opposing sidewalls 46 of the cooking container 36. The handles 44 may be movable or removably connected thereto, such as via one or more fasteners for example, or alternatively, may be integrally formed with a sidewall 46 of the cooking container 36. Although the cooking container 36 illustrated and described herein has two handles 44, embodiments having a single handle, more than two handles, or no handles are also contemplated herein. Further, any suitable configuration of the cooking container 36 and/or handles 44 is within the scope of the disclosure.

The cooking container 36 and/or the liner 34 may be configured to properly position the cooking container 36 within the liner 34. In an embodiment, best shown in FIG. 4 and FIG. 6, one or more bumpers 48 extend inwardly from the liner 34 to engage the exterior surface 42 of the cooking container 36. The bumpers 48 may be spaced equidistantly about the inner periphery of the liner 34 to center the cooking container 36. However, embodiments where the bumpers 48 are not equidistantly spaced, or embodiments having only a single bumper 48 are also contemplated herein.

Alternatively, or in addition, the cooking container 36 may be contoured to facilitate positioning of the cooking container 36 within the liner 34. In an embodiment, a cross-sectional area of the cooking container 36 varies over the height of the cooking container 36. For example, a step 50 may be formed in a central portion of the sidewall 46 of the cooking container 36. Accordingly, a first portion of the cooking container 36 extends between an upper surface 52 of the cooking container 36 and the step 50, and a second portion of the cooking container 36 extends between the step 50 and a bottom 54 of the cooking container 36. As a result of the horizontal offset created by the step 50, the diameter of the first portion of the cooking container 36 is larger than the diameter of the second portion of the cooking container 36. In an embodiment, the step 50 is located near, but offset from, the bottom 54 of the cooking container 36. Further, the step 50 may extend over the entire inner periphery of the cooking container 36, or alternatively, over only select portions thereof.

In an embodiment, the step 50 is sized and shaped to cooperate, for example overlap or mate with, another component of the cooking system 20 to position the cooking container 36 relative to the base 22. For example, a spacer 56 (best shown in FIG. 6) may be mounted within the hollow interior 32 defined by the liner 34, and the step 50 may directly engage the spacer 56 when the cooking container 36 is installed within the liner 34. Alternatively, a ledge 58 as shown in FIG. 7, complementary to the step 50, may be affixed to or integrally formed with the liner 34 such that when the cooking container 36 is inserted into the liner 34, the step 50 and ledge 58 align to seat the cooking container 36 in a desired manner.

One or more accessories or support bodies (to be described in more detail below), may be compatible for use with the cooking system 20. In such embodiments, the accessories or support bodies may be receivable within the hollow interior 32 of the liner 34, or alternatively, within the interior of the cooking container 36. In an embodiment, an accessory or support body compatible for use with the cooking container 36 is supported by the step 50 of the cooking container 36 rather than the bottom 54 thereof. However, other accessories or support bodies that may be supported by the bottom 54 of the cooking container 36 are also within the scope of the disclosure. Any accessory or support body as discussed herein may include a support surface for supporting food thereon. The support surface will generally be the upper surface of the support body, and will be exposed to the cooking zone (more on this below).

Referring with more detail to the lid 24, it should be noted that the lid 24 is connectable to a surface of the cooking container 36 and/or housing 26 to close off entry to the interior 38 of the cooking container 36. Accordingly, a cooking volume may be defined between the interior 38 of the cooking container 36 and heating element 82 or an end of the closed lid 24 operable to engage the base 22, or alternatively, between the hollow interior 32 defined by the liner 34 and the heating element 82 or the end of the closed lid 24 operable to engage the base 22. In an embodiment, a diameter of the lid 24 is generally complementary to a diameter of the housing 26 such that the lid 24 covers not only the cooking container 36, but also an upper surface 60 of the housing 26.

The lid 24 is movable relative to the base 22 between an open position and a closed position to selectively cover the hollow interior 32. For example, the lid 24 may be distinct and separable from the base 22, or the lid 24 may be movably connected to the base 22. One or more fastening mechanisms (not shown) may, but need not be used to secure the lid 24 to the base 22 when the lid 24 is in the closed position. Any suitable type of fastening mechanism capable of withstanding the heat associated with the cooking system 20 is considered within the scope of the disclosure.

In the illustrated, non-limiting embodiment, the lid 24 is pivotable or rotatable relative to the base 22 about a pivot axis P. As shown, the lid 24 may be rotatable about a pivot axis P positioned adjacent a lower surface 62 of the housing 26. In some embodiments, the base 22 includes a rigid pivot arm 64 positioned adjacent a back surface 66 of the housing 26 and having a first end 68 connected to the housing 26 about a pivot axis P. A second, opposite end 70 of the pivot arm 64 is connected to a back surface 72 of the lid 24. Accordingly, as the pivot arm 64 is rotated about the pivot axis P in a first direction, indicated by arrow O, the lid 24 is rotated away from or out of engagement with an upper surface 60 of the housing 26 to expose the hollow interior 32. Similarly, as the pivot arm 64 is rotated about the pivot axis P in a second direction, indicated by arrow C, the lid 24 is rotated toward or into engagement with the upper surface 60 of the housing 26 or the upper surface 52 of the cooking container to seal or cover the cooking container 36. By positioning the pivot axis P near a lower surface 62 of the housing 26, the sizing envelope of the cooking system 20 when the lid 24 is in the open position may be limited. However, in other embodiments, the pivot axis P and connection of the lid 24 to the base 22 may be arranged at or near the upper surface 60 of the base 22.

In an embodiment, the base 22 of the cooking system 20 may additionally include a support 74 extending from the housing 26. The support 74 may be mounted to the side of the housing 26 about which the lid 24 is positioned when in the open configuration, to further stabilize the cooking system 20 when the lid 24 is open. In embodiments including both a support 74 and a pivot arm 64, the first end 68 of the pivot arm 64 may be coupled to the support 74, as shown in FIG. 4, rather than to the housing 26. Accordingly, in such embodiments, the pivot axis P is laterally offset from the housing 26. In an embodiment, the lid 24 is rotatable about the pivot axis P between about 40 degrees and about 80 degrees, between about 50 degrees and about 70 degrees, and more specifically about 62 degrees for example, to achieve a desirable angle θ (see FIG. 4) between an end 76 of the lid 24 opposite the pivot arm 64 and the upper surface 60 of the housing 26. In an embodiment, the angle θ is between about 65 degrees and about 95 degrees, between about 70 degrees and about 90 degrees, and more specifically, about 80 degrees.

In the illustrated, non-limiting embodiment, one or more handles 78 extend outwardly from a housing 80 of the lid 24 to provide a user with a location to easily grasp the lid 24 for movement between the open and closed position. Although a single handle 78 mounted generally near a front of the lid 24 is shown, embodiments having multiple handles, or alternatively, no handles are also within the scope of the disclosure. The housing 80 and/or the one or more handles 78 may be integrally or separately formed, such as from a molded plastic material for example.

To enhance a user's access to the hollow interior 32 of the housing 26 or the interior 38 of the cooking container 36, in an embodiment, the housing 26 is configured to move, for example translate and/or rotate, relative to a supporting surface, such as a countertop for example. In an embodiment, the base 22 includes a track defining a path of movement of the housing 26. The housing 26 may include a component complementary to and engaged with the track. Movement of the housing 26 relative to the supporting surface may be driven by the lid 24. For example, as the lid 24 is transformed from a closed position to an open configuration, such as via rotation about the pivot axis P, the housing 26 may similarly move relative to the supporting surface from a retracted position to an extended position. Movement of the lid 24 from an open position to a closed position will similarly cause the housing 26 to move from an extended position to a retracted position. In an embodiment, this movement of the housing 26 may occur as a result of engagement between a portion of the pivot arm 64 and a corresponding portion of the housing 26.

Referring now to FIG. 3 and FIG. 10, the cooking system 20 includes at least one heating element 82 operable to impart heat to the cooking volume during one or more modes of operation of the cooking system 20. In the illustrated, non-limiting embodiment, the at least one heating element 82 is positioned generally at or above an upper extent or surface 52 of the cooking container 36, such as proximate a center of the interior 38 of the cooking container 36 for example. In the embodiment as shown the at least one heating element 82 is mounted within the lid 24, and therefore completely outside of the cooking container 36, and vertically offset from the upper extent or surface 52 thereof. However, it should be understood that a heating element located at any suitable location is within the scope of the disclosure.

The at least one heating element 82 may be capable of performing any suitable type of heat generation. For example, a heating element 82 configured to heat the cooking container 36 or one or more food items located within the interior 38 of the cooking container 36 via conduction, convection, radiation, and induction are all within the scope of the disclosure. In the illustrated, non-limiting embodiment, the heating element 82 is a convective heating element, and the cooking system 20 additionally includes an air movement device 84, such as a fan for example, operable to circulate air within the cooking volume. The air is heated as it flows along its path of circulation, such as by flowing over a portion of the at least one heating element 82. In the illustrated, non-limiting embodiment, the air movement device 84 is driven by a motor 86 having a separate cooling mechanism coupled thereto. Further, the cooking system 20 may include a vent for exhausting hot air generated by operation of at least one of the air movement device 84, the motor 86, and the separate cooling mechanism to the exterior of the cooking system 20. Although the vent is illustrated as being formed in the lid 24, embodiments where the vent is formed in the base 22 of the cooking system 20 are also contemplated herein. In an embodiment, a guard 88 (see FIG. 2) for restricting projectile matter, such as oil for example, from contacting the heating element 82 is positioned directly adjacent the heating element, between the heating element and the interior 38 of the cooking container 36.

As previously mentioned, a support body 100 having a support surface for supporting food thereon is removably mounted within the interior 38 of the cooking container 36. In an embodiment, the support body 100 is a grill plate, which will be described in more detail below.

With continued reference to FIGS. 3 and 6, and further reference to FIG. 16, in an embodiment, the support body 100 positioned within the interior 38 of the cooking container 36 at least partially defines a cooking zone Z within the cooking volume. An upper surface of the support body 100 defines a bottom or lower end of the cooking zone Z. One or more accessories, to be described in more detail below, may be installed in place of the grill plate 100 (as a support body themselves) or in overlapping arrangement with the upper surface of the grill plate 100. In embodiments where a non-grill plate accessory is installed within the cooking container 36, a support surface of the uppermost accessory on which food is receivable, defines the bottom of the cooking zone Z. The cooking zone Z is further defined by one or more sidewalls of the accessory and/or the interior 38 of the cooking container 36. In addition, the cooking zone Z extends from the cooking surface of the grill plate 100 or accessory mounted thereon to either the heating element 82, or alternatively, to the guard 88.

With reference again to FIG. 1, a control panel or user interface 90 of the cooking system 20 is positioned adjacent one or more sides of the housing 26 of the base 22 or one or more sides of the housing 80 of the lid 24. The control panel 90 includes one or more inputs 92 associated with energizing the heating element 82 of the cooking system 20 and for selecting various modes of operation of the cooking system 20. One or more of the inputs 92 may include a light or other indicator to show that the respective input has been selected. The control panel 90 may additionally include a display 94 separate from and associated with the at least one input 92. However, embodiments where the display 94 is integrated into the at least one input 92 are also contemplated herein.

Operation of the one or more inputs 92 will be described in more detail below. As shown in FIG. 11, a control system 96 of the cooking system 20 includes a controller or processor 98 for controlling operation of the heating element 82 (and air movement device 84 including the motor 86 and/or fan associated therewith), and in some embodiments for executing stored sequences of heating operation. The processor 98 is operably coupled to the control panel 90 and to the heating element 82 and the air movement device 84. In an embodiment, the processor 98 and/or another portion of the control system 96 is mounted adjacent the back surface 66 of the housing 26, and in some embodiments within the support 74.

In addition, the cooking system 20 may include one or more sensors S for monitoring one or more parameters associated with airflow temperature the heating element 82, the lid 24, the cooking volume, the grill plate 100, and/or and accessory mounted within the cooking volume during a cooking operation. Accordingly, operation of the cooking system 20, and in particular of the one or more heating elements 82, may be regulated in response to the parameters sensed by the one or more sensors S. In an embodiment, the one or more sensors S includes a temperature sensor arranged in communication with the processor 98. In an embodiment, the temperature sensor(s) S, such as a thermistor of thermistors for example, are positioned in one or both of the liner 34 and the cooking container 36 (or there between), such as adjacent the step 50 formed in the cooking container 36 for example. In embodiments where a temperature sensor S is hardwired to the control system 96, one or more wires connecting the temperature sensor S to the processor 98 may be embedded within the housing 26, such as between the housing 26 and the liner 34 for example.

The temperature sensor(s) S may directly contact the exterior surface 42 of the cooking container 36 to determine the temperature of the cooking container 36, or alternatively, may extend through body of the cooking container 36 for engagement with the support body 100, i.e. the grill plate in the embodiment shown in FIG. 6, or with an accessory arranged within the interior 38 of the cooking container 36 in other embodiments. As is best shown in FIG. 6, the temperature sensor S may be coupled to or at least partially supported by the spacer 56. Alternatively, in embodiments where the cooking system 20 includes a ledge 58, the temperature sensor S may be supported at least partially by the ledge 58, as shown in FIG. 7.

In yet another other embodiment, best shown in FIGS. 8 and 9, the temperature sensor S is integrated into the cooking container 36 and is operable to contact and sense the temperature of the support body 100 (such as the grill plate). As shown, the temperature sensor S may be mounted upwardly adjacent the step 50, within the interior 38 of the cooking container 36 via an aluminum plate 53 and a metal bracket 55 for example. A seal 57, such as formed from silicone for example, may seal the plate 53 to the cooking container 36. The temperature sensor S may be located at a position offset from the metal bracket 55 to prevent overheating of the temperature sensor S. In such embodiments, the gap 59 between the temperature sensor S and the metal bracket 55 may be filled with a thermal paste. It should be understood that the various configurations of the temperature sensor S illustrated and described herein are intended as an example only and that other configurations suitable for monitoring and communicating (to the control system 96) a temperature of at least one of the cooking container 36, the support body 100, i.e. the grill plate in the embodiment shown in FIG. 6, or an accessory positioned within the interior 38 of the cooking container 36 are also contemplated herein.

In addition to the temperature sensor(s) S used to monitor the temperature of the support body 100, the cooking system 20 may also employ a further temperature sensor or sensors (also indicated as S) to sense the temperature of the air provided to the interior 38 of the cooking container 36. In such embodiments, a first temperature sensor or sensors may be mounted as previously described, for example to contact a bottom or lower surface of the grill plate 100, and a second temperature sensor or sensors may be located within the lid 24, generally adjacent the air movement device 84, such that the temperature sensor is located directly within the heated airflow expelled from air movement device 84. One or more operating parameters of the cooking system 20 may be adjusted via, for example, a control algorithm accessible by the processor 98 in response to the temperature detected by the one or more temperature sensors S. In an exemplary embodiment, the speed of the air movement device 84 may be adjusted, or alternatively, the power provided to the heating element 82 may be increased or decreased to achieve a desired temperature.

In embodiments of the cooking system 20 including temperature sensors S positioned in different locations, adjustment of an operating parameter, such as operation of the heating element 82 for example, may be performed using the control algorithm in response to the temperature of the heated airflow, measured by the temperature sensor S disposed in the heated airflow. For example, power provided to the heating element 82 may be increased if the sensed airflow temperature is below a set point, and the power provided to the heating element 82 may be reduced or ceased completely if the sensed airflow temperature is above a set point, thereby allowing the interior 38 of the cooking container 36 to cool. In an embodiment, the temperature sensor S positioned proximate the support body 100 is operable to provide smoke control and indicate when the temperature of the grill plate 100 is approaching a temperature associated with the generation of smoke (also known as the smoke point). The smoke point will vary based on the type of food and/or fat positioned within the interior 38. An example of the smoke point of common foods is shown below:

Operation of the cooking system 20 is impacted by the temperature sensor S proximate the grill plate 100 if the sensed temperature of the grill plate 100 is above a threshold stored within a memory embedded within or accessible by the processor 98, for example associated with a smoke point. All of the above smoke points may be stored in the processor memory and used as a set threshold. In addition, modes of operation are contemplated. For example, in a low mode of operation, the temperature threshold of a surface of the grill plate 100 is about 345° F., in a medium mode of operation, the temperature threshold of a surface of the grill plate 100 is about 375° F., and in a high mode of operation, the temperature threshold of a surface of the grill plate 100 is about 410° F. The thresholds indicated herein are intended as an example only, and it should be understood that other temperatures may be selected for any of the various modes of operation.

In at least one mode of operation, such as a maximum temperature mode of operation, the cooking system 20 is configured to ignore or disregard the temperature of the grill plate 100 detected by the temperature sensor S proximate thereto. As a result, in the maximum temperature mode, the temperature of the grill plate 100 may exceed the smoke point. Although operation is described herein with respect to use of the temperature sensor proximate the grill plate 100 to monitor the temperature of the grill plate 100, similar control of the cooking system 20 may be performed in embodiments where this temperature sensor S is operable to monitor the temperature of either the cooking container 36 or the temperature of an accessory mounted within the interior 38 of the cooking container 36.

In an embodiment, at least one input 92 on the control panel 90 is an on/off button which allows the user to activate or deactivate the control panel 90. When the control panel 90 is deactivated, none of the one or more heating elements 82 are energized. In an exemplary embodiment, the at least one input 92 is operable to select one or more manual modes of operation of the heating element 82. Alternatively, or in addition, at least one input 92 is operable to select a stored sequence of operation of the heating element 82. In some cases, the stored sequences may be particularly well suited for a given method of food preparation and/or for particular ingredients or types of ingredients. The plurality of stored sequences associated with the at least one input 92 may be stored within a memory accessible by the processor 98. Alternatively, the plurality of stored sequences may be stored remotely from the cooking system 20, and may be accessed by the processor 98, such as via wireless communication for example.

In addition, a user may be able to enter a time associated with operation of the cooking system 20 in a desired manual mode. The time may be entered via the same input 92 or a separate input 92 as used to select a mode of operation. Further in embodiments where the cooking system 20 is in a mode configured to perform a stored sequence in response to selection of one of the inputs 92, the display 94 may indicate a time remaining on the display 94. Temperature or other parameters may also be entered via inputs 92.

The at least one input 92 may include a distinct start button intended to initiate operation in a desired mode, a distinct stop button to cease all operation, or a stop/start button intended to initiate and cease functions. Alternatively, the cooking system 20 may be operable to automatically start operation after a predetermined time has elapsed once an input 92 has been selected and any necessary information has been provided to the control panel 90. Alternatively, one or more of the other inputs 92, such as the knob for example, may be operable, such as by pushing the knob towards the control panel 90, to start and stop operation of the cooking system 20, regardless of whether the cooking system 20 is following a stored sequence or is in a manual mode.

The one or more inputs 92 are operable to initiate operation of the cooking system 20 in a plurality of cooking modes. In an embodiment, a first cooking mode of the cooking system 20 is operable to cook a food item located within the cooking volume via both a non-contact cooking operation and a contact cooking operation. As used herein, the term “non-contact cooking operation” includes any cooking operation where a heating element or heat source is not arranged in direct or indirect contact with a food item, such as, but not limited to, convective and radiant heating. Similarly, the term “contact cooking operation” includes a cooking operation where heat is transmitted via direct or indirect contact between a heating element or heat source and a food item, such as, but not limited to, conductive and inductive cooking. For example, the first cooking mode may cook a food item via a combination of both convection and conduction cooking; however, it should be understood that any combination of non-contact and contact cooking operations are contemplated herein.

Operation in the first cooking mode involves the use of various components, such as the heating element 82 and support body 100, such as the grill plate for example, receivable within the interior of the liner 34, or alternatively, within the interior 38 of the cooking container 36. With reference now to FIG. 12, an example of the grill plate 100 is shown in more detail. The grill plate 100 includes a body 102 having a plurality of through holes or openings 104 formed therein. The body 102 of the grill plate 100 is sized such that the grill plate 100, when installed within the interior 38 of the cooking container 36, is in contact with and supported by the step 50 (See FIG. 10). Accordingly, a clearance is defined between the bottom 106 of the grill plate 100 and the bottom 54 of the cooking container 36. Grease, oil, and other runoff liquids generated during a cooking operation may flow through the openings 104 formed in the body 102, to collect beneath the grill plate 100, at the bottom 54 of the cooking container 36. In an embodiment, the diameter of the grill plate 100 is substantially equal to the inner diameter of the first portion of the cooking container 36. As a result, when installed within the cooking container 36, an outer perimeter of the grill plate 100 generally abuts or is minimally offset from (about 1 mm of less) the interior surface 40 of the cooking container 36.

As shown best in FIG. 12, a plurality of ribs 108 may extend from an upper surface 110 of the body 102. The ribs 108 are spaced apart from one another to define a plurality of channels 112 formed between adjacent ribs 108. The ribs 108 may be integrally formed with the upper surface 110, or alternatively, may be affixed thereto. Accordingly, when one or more food items are positioned on the food supporting surface 114 defined by the ribs 108, the food is offset from the upper surface 110 of the body 102. Each of the plurality of ribs 108 may be identical, or alternatively, may vary in size or shape based on the position of the rib 108 relative to the body 102. In the illustrated, non-limiting embodiment, the plurality of ribs includes longer ribs 116, intermediate ribs 115, and shorter ribs 117. The longer ribs 116 extend radially outwardly from a center opening 118 formed in the body 102. The intermediate ribs 115 and shorter ribs 117 also extend radially outwardly from areas disposed closer to the edges of the body 102 (the intermediate ribs 115 extending from concentric opening 121 and the shorter ribs 117 extending from concentric opening 123), with all of the ribs 108 generally extending to the outermost edges of the body 102.

In an exemplary embodiment, some or all of the ribs 108 create a diffusing structure operable to diffuse an air flow provided thereto. The diffusing structure described herein functions not only to slow the speed of an air flow, but also to reduce the rotation of the airflow as is passes through the diffusing structure. As shown in FIG. 12, each of the ribs 108 of the grill plate 100 forms a portion of the diffusing structure. However, in other embodiments only a portion of the ribs 108, for example only the longer ribs 116, or alternatively, the longer ribs 116 and the intermediate ribs 117, cooperate to diffuse an air flow provided to the grill plate.

One or more handles 120 may be associated with the grill plate 100 to allow a user to easily grasp and manipulate the grill plate 100. In the illustrated, non-limiting embodiment, the grill plate 100 has two handles 120 extending from the upper surface 110 of the base 102, adjacent opposing sides of the grill plate 100. The handles 120 may be connected to a rib 108 or directly to the body 102 of the grill plate 100. Although the handles 120 are illustrated as being integrally formed with the grill plate 100, embodiments where the one or more handles 120 are affixed to the grill plate 100 are also within the scope of the disclosure.

The grill plate 100 may be made of any suitable metal material, such as iron, steel, aluminum or any suitable ferromagnetic material. Further, in some embodiments, at least a portion of the grill plate 100 may be coated with a non-stick material, such as Teflon for example, to prevent food items from sticking to the grill plate 100.

With continued reference to FIG. 12 and to the first cooking mode, at the start of the first cooking mode, the grill plate 100 is mounted within the cooking container 36 and the lid 24 covers the upper extent or surface 52, 60 and hollow interior 32, 38 of the housing 26 and the cooking container 36, respectively. When utilizing the cooking system 20 in the first cooking mode, the processor 98 initiates operation of the heating element 82 located remotely from the grill plate 100 to heat the grill plate 100. In an embodiment, the air movement device 84 is also operated to circulate the hot air within the cooking volume as represented by arrows in FIG. 10. As shown, the air output from the air movement device 84 is drawn through the heating element 82 and into the air movement device 84 from a center of the cooking volume. The heated air is exhausted radially and has a circular flow or spin, best shown in FIG. 10A, similar to the rotation of the air movement device 84. Due in part to the spin of the heated air and deflection thereof by interior surfaces of the lid 24, the air flows downwardly into the cooking volume along the interior surface 40 of the cooking container 36.

As the air flow approaches the step 50 formed in the cooking container 36, the air flow is received generally adjacent the outer periphery of the grill plate 100. The diffusing structure of the grill plate 100 halts the downward movement of the air flow and directs the air flow radially inwardly through the plurality of channels 112 defined between the ribs 108. The curved configuration of the ribs 108 and channels 112 of the diffusing structure slows the rotation to the air flow while simultaneously directing the air flow generally horizontally towards the center of the grill plate 100 where one or more food items are typically positioned. As a result, rotation of the flow of air output from the plurality of channels at a relative center of the grill plate 100 is stopped altogether or at least less than the rotation of the flow of air that enters the plurality of channels 112 at the outer periphery of the grill plate 100. The flow of air exiting the channels 112 flows upwardly from beneath a food item and, around an exterior surface of the food item before being drawn back up and through the heating element 82 by the air movement device 84. This movement of the air through the cooking volume to convectively cook the food items (i.e. non-contact cooking) may be facilitated in part by the configuration of the diffusing As the heated air flows through the channels 112 and over the surface of the grill plate 100, heat from the air is transferred to the grill plate 100, thereby increasing the temperature of the grill plate 100. As previously described, the grill plate 100 is formed from a conductive, metal material.

In an embodiment, the mass of the grill plate 100 is selected such that during operation in the first cooking mode, the grill plate 100 achieves and maintains a temperature, after an initial “preheating” period, sufficient to cause a Maillard reaction in the food located within the cooking volume. The temperature of the grill plate 100 necessary to achieve the Maillard reaction is at least 285° F. In an embodiment, the preheating period is a period of time required to heat the grill plate 100 to a temperature where the Maillard reaction will occur, i.e. 285° F. or warmer. In embodiments where the preheating period increases the temperature of a grill plate 100 initially at room temperature to a temperature where the Maillard reaction will occur is less than about 20 minutes, less than about 15 minutes, or less than about 10 minutes. In an embodiment, a temperature sensor S of the cooking system 20 is operable to monitor the temperature of the cooking container 36 and/or the temperature of the grill plate 100. Accordingly, the display 94 may indicate to a user that the “preheat” operation is complete and that food is ready to be received within the cooking volume in response to the determining that the temperature of the grill plate 100 as detected by the temperature sensor S has reached a minimum temperature necessary to achieve the Maillard reaction.

Because weight and cost are typically directly proportional, it is desirable to minimize the weight of the grill plate 100. As a result, the thermal mass of grill-like elements, such as burners used in a stove for example, are insufficient to achieve and maintain a temperature required to initiate the Maillard reaction, specifically when heated via convection or radiation. In an embodiment, the mass of the grill plate 100 is between about 200 grams and about 3 kg, and more specifically, between about 300 g and about 3 kg, about 400 grams and about 3 kg, about 500 g and about 3 kg, about 600 g and about 3 kg, about 700 g and about 3 kg, about 800 g and about 3 kg, about 900 g and about 3 kg, about 1000 g and about 3 kg, about 1.1 kg and about 3 kg, about 1.2 kg and about 3 kg, about 1.3 kg and about 3 kg, about 1.4 kg and about 3 kg, 1.5 kg and about 3 kg, 1.6 kg and about 3 kg, 1.7 kg and about 3 kg, 1.8 kg and about 3 kg, 1.9 kg and about 3 kg, 2.0 kg and about 3 kg, about 2.1 kg and about 3 kg, about 2.2 kg and about 3 kg, about 2.3 kg and about 3 kg, about 2.4 kg and about 3 kg, about 2.5 and about 3 kg, about 2.6 and about 3 kg, about 2.7 and about 3 kg, about 2.8 and about 3 kg, or about 2.9 kg and about 3 kg.

During the first cooking mode, after the preheating period is completed, one or more food items are positioned within the cooking volume, in direct contact with the support surface 114 of the grill plate 100 to perform a grilling operation. Heat from the grill plate 100, and more specifically from the ribs 108, is transferred to the food items, such as via conduction (i.e. contact cooking). Because the temperature of the grill plate 100 is above 285° F., and therefore the Maillard reaction occurs, browning in the form of grill or sear marks is formed at the surfaces of the food arranged in direct contact with the ribs 108 of the grill plate 100. It should be understood that in embodiments where only a portion of the ribs 108 form part of the diffusing structure, the ribs 108 that are not part of the diffusing structure are operable to transfer heat to the food. Further, the ribs 108 that define the diffusing structure transfer heat to the food.

During operation in the first cooking mode, including after the grill plate 100 has preheated to a desired temperature, the temperature sensor S may continuously or selectively sample the temperature of the cooking volume or of the grill plate 100 and adjust operation of the cooking system 20 accordingly. For example, upon determining that the temperature of the grill plate 100 is approaching a maximum threshold, the processor 98 may de-energize the heating element 82 until the temperature has fallen to an acceptable level. In such embodiments, the maximum threshold may be smoking point of the food positioned within the cooking volume. Similarly, upon determining that the temperature of the grill plate 100 is approaching a minimum threshold, such as a lowest possible temperature to achieve a Maillard reaction, the processor 98 will adjust one or more operating parameters of the cooking system 20, such as the speed of the air circulation, and/or the power provided to the heating element 82.

Although the grill plate 100 is illustrated and described as being heated in the first cooking mode by a heating element 82 located remotely therefrom (i.e. within the lid) such that the food items being cooked are disposed between the at least a portion of the heating element 82 and at least a portion of the grill plate 100, in other embodiments, the cooking system 20 may include another heating element 122 (see FIG. 13), distinct from the heating element 82, and operably coupled to the grill plate 100. The first and second heating elements 82, 122 are operable independently or in combination to apply one or more predetermined power settings to cook the food products within the cooking container 36. In an embodiment, the heating element 122 is embedded within the grill plate 100. Alternatively, the heating element 122 may be embedded within the housing 26 and operably coupled to the grill plate 100 when the grill plate 100 is installed within the hollow interior 32 of the liner 34 or the interior 38 of the cooking container 36. Accordingly, in an embodiment, during operation in the first cooking mode, both the heating element 82 and the heating element 122 are operational and impart heat to the cooking volume.

In embodiments where a heating element 122 is embedded within the housing 26 adjacent a sidewall 46 of the cooking container 36, the heating element 122 may define a portion of the cooking zone Z. Accordingly, because the bottom of the cooking zone Z is defined by the cooking surface 114 of the grill plate 100 or an uppermost surface of an accessory, at least a portion of the cooking zone Z, illustrated in the shaded region of FIG. 17, and any food in contact with the surface 114 is disposed between a portion of the food support surface 114 and a portion of the heating element 122.

Further, the first cooking mode may additionally be used to perform cooking operations other than “grilling.” As previously described, an accessory may be mounted in overlapping arrangement with the upper surface 114 of the grill plate 100 such that heat is transferred from the grill plate 100 to the accessory. Alternatively, the accessory may be mounted within the interior 38 of the cooking container 36 absent the grill plate 100, such that the accessory functions as a support body as described herein. Examples of such accessories include a griddle 123 as shown in FIG. 14, a crisping basket 130 shown in FIG. 15, and crisping plate 132 (FIGS. 3 & 5).

In an embodiment, the cooking system 20 is additionally operable in a second cooking mode where the heating element 82 is employed to perform a non-contact heating operation, such as a convective or radiative heating operation. Accordingly, in embodiments where the cooking system 20 additionally includes heating element 122, in the second cooking mode, heating element 122 is not operable. Suitable cooking operations in the second cooking mode may include, but are not limited to air frying, broiling, baking/roasting, and dehydrating. In the second cooking mode, the grill plate 100 is typically not positioned within the interior 38 of the cooking container 36. However, embodiments where the grill plate 100 is disposed within the interior 38 of the cooking container 36 in the second mode are also contemplated herein.

In the second cooking mode, in embodiments absent the grill plate 100, any suitable accessory may be mounted within the cooking container 36 to define the support surface of the cooking zone Z. For example, the crisping basket 130 is positionable within the interior 38 of the cooking container 36, and may be supported by the step 50, or alternatively, by the bottom 54 of the cooking container 36. One or more dimensions of the crisping basket 130 are smaller than the interior 38 of the cooking container 36 such that an annulus is defined between a sidewall of the crisping basket 130 and an interior surface 40 of the cooking container 36. A plurality of openings 134 formed in a bottom 136 of the crisping basket 130 allow a flow of air to circulate there through.

The crisping plate 132 (FIGS. 3 and 5) may have a configuration similar to the crisping basket 130. As shown, the crisping plate 132 includes a base 138 having a first side 140 and a second side 142 extending from the base 138, and a plurality of openings 144 formed in the base 138. An annulus 146 may similarly be formed between the first and second sides 140, 142 of the crisping plate 132 and an interior surface 40 of the cooking container 36.

In the embodiment of FIG. 3, a diffuser 148 having one or more vanes 150 is positioned adjacent or integrated with the crisping plate 132. As shown, the vanes 150 extend generally perpendicular from the bottom of the base 138. In instances including a plurality of vanes 150, the vanes 150 may have similar or different configurations. Further, the plurality of vanes 150 may be spaced about the base 138 of the crisping plate 132 and may have similar or have varying orientations. In the illustrated, non-limiting embodiment, the crisping plate 132 includes four vanes 150, and adjacent vanes 150 are spaced equidistantly about a center of the base 138 and are rotated ninety degrees relative to one another. However, it should be understood that in other embodiments, the crisping plate 132 need not have a diffuser 148 associated therewith.

During operation in the second cooking mode, the air movement device 84 may be operable to circulate a heated air flow through the cooking volume. As previously described, the air movement device 84 is operable to draw air upwards, through the adjacent heating element 82 and expel the hot air outwardly, where it is redirected downwardly toward the cooking volume. The hot air flows to the bottom 54 of the cooking container 36, such as through an annulus formed between an accessory, such as the crisping plate 132 or the crisping basket 130 and the cooking container 36. The hot air is deflected off the bottom 54 of the cooking container 36, and drawn by the air movement device 84 through the openings formed in the accessory. In some embodiments where the accessory includes a lower diffuser, such as the crisping plate 132 for example, the hot air may flow over the vanes of the diffuser, and a rotational motion may be imparted to the hot air, thereby creating a vortex as the air passes through the openings of the accessory. After flowing over an exterior of the food items within the cooking container 36, the air is drawn back through the heating element 82 and into the air movement device 84 for further circulation.

In an embodiment, the air movement device 84 of the cooking system 20 is a variable speed fan operable at a plurality of rotational speeds. In an embodiment, the operational speed of the air movement device 84 may vary based on the cooking mode selected. For example, the speed of the air movement device 84 during operation in a first cooking mode may be different than the speed of the air movement device 84 during operation in a second air-fry mode. The operational speed of the air movement device 84 may be controlled by the processor 98 in response to one or more inputs 92, including selection of a cooking mode. However, the processor 98 may also be configured to adjust the operational speed of the air movement device 84, or alternatively, the power supplied to the one or more heating elements 82, 122, to control the temperature and/or pressure within the interior 38 of the cooking container 36.

In some embodiments, the cooking system 20 is operable in more than two cooking modes. For example, in embodiment where the cooking system 20 includes a heating element 122 operably coupled to the grill plate 100 and separate from heating element 82, the cooking system 20 may be operable in a third cooking mode. In the third cooking mode, the heating element 122 is operational and the heating element 82 is generally de-energized. In the third cooking mode, the heating element 122 is operable to perform a contact heating operation, such as slow cooking, searing, and sautéing for example. In such embodiments, the heating element 122 may be operable to a heat the cooking container 36 absent the grill plate 100, and alternatively or in addition, heat one or more accessories positioned in overlapping arrangement with the grill plate 100.

The cooking system 20 illustrated and described herein provides an enhanced user experience by combining the functionality of several conventional household products into a single user-friendly device.
